Since large impedance contrasts exist between eclogite and other rocks, it is effective that the VSP profiles are used to calibrate geological horizons of seismicreflections.
The accurate interpretation shows that such domal bodies are the seismicreflections of non-reef-bank deposits of low angle thrust faults, slope slump accumulative zones and turbidite fans.
精细解释表明,此类丘状体是低倾角逆断层构造、斜坡滑塌堆积及浊积扇等非礁滩沉积体的地震响应。

So it is often difficult to identify the reflections from the channel sand body on conventional seismic sections.
